A 3-page worksheet product designed to cover the basic evolutionary concept For speciation to occur, two new populations must be formed from one original population, and they must evolve in such a way that it becomes impossible for individuals from the two new populations to interbreed. Which of the following traits may be acted on by natural selection? %PDF-1.6 % Inform students that they will explore the evidence for evolution and how we can use phylogeny to understand the relationships between species. In some cases a polyploid individual will have two or more complete sets of chromosomes from its own species in a condition called autopolyploidy (Figure 11.17). Island archipelagos like the Hawaiian Islands provide an ideal context for adaptive radiation events because water surrounds each island, which leads to geographical isolation for many organisms (Figure 11.16). From one point of origin, many adaptations evolve causing the species to radiate into several new ones.

Scientists have discovered more than 1/2 of all plant species studied relate back to a species evolved through polyploidy. In this activity, students formulate and evaluate a hypothesis about the amount of time necessary for natural selection by predation. Also Read: Concept of Species. using to identify the different plant species? The divergence of species is thought to result primarily from the geographic isolation of a population, especially when confronted with environmental conditions that vary from those experienced by the rest of the species, and from the random change in the frequency of certain alleles (known as, Timeless meditations on Earths fragility, and the damage humans do, New Fish Data Reveal How Evolutionary Bursts Create Species, When Evolution Is Infectious - Issue 90: Something Green, Speciation in the Kangaroo Rat, Dipodomys ordii, Systematics of Megachiropteran Bats in the Solomon Islands. then you must include on every physical page the following attribution: If you are redistributing all or part of this book in a digital format, Summarize Darwin's contributions to our current understanding of evolution.

If this group of fish continued to remain separate from the first population, eventually sympatric speciation might occur as more genetic differences accumulated between them. Our mission is to improve educational access and learning for everyone. 2. In the example shown, a normal gamete from one species fuses with a polyploid gamete from another. Different histories of genetic drift, enhanced because the populations are smaller than the parent population, will also lead to divergence. Allopatric speciation, meaning speciation in other homelands, involves a geographic separation of populations from a parent species and subsequent evolution. This worksheet focuses more on speciation and reproductive isolation. <> The topics covered include adaptation, natural selection by predation, speciation, and reproductive barriers. Sympatric speciation may also take place in ways other than polyploidy. Figure 11.18 illustrates one possible way an allopolyploidy can form. 4 0 obj 2023. If two flying insect populations took up residence in separate nearby valleys, chances are that individuals from each population would fly back and forth, continuing gene flow. WebA biology resource site for teachers and students which includes lesson plans, student handouts, powerpoint presentations and laboratory investigations. This segment emphasizes how microevolution (evolutionary changes within a species) can lead to the formation of new species (macroevolution). It is hypothesized that either through mutation or a behavioral mistake, flies jumped hosts and met and mated in apple trees, subsequently laying their eggs in apple fruit.

The northern spotted owl has genetic and phenotypic differences from its close relative, the Mexican spotted owl, which lives in the south (Figure 11.15). Researchers have found hundreds of sympatric speciation events in these fish, which have not only happened in great number, but also over a short period of time. These individuals would immediately be able to reproduce only with those of this new kind and not those of the ancestral species. Scaffold the activity for younger or lower performing students by instructing them to work collaboratively to build their phylogenetic tree. If the two isolated populations are brought back together and the hybrid offspring that formed from matings between individuals of the two populations have lower survivorship or reduced fertility, then selection will favor individuals that are able to discriminate between potential mates of their own population and the other population. hb```LVw eaXa70*NoIwH9- {GGl`` d^>i@Z@123N[!`PZ, !_4Z@I 9>?n]/2'DQ.*!
